Fabrication of nanoporous high index thin films for aviation industry

全球航空业在增加对飞机的激光攻击方面面临着巨大的挑战。这种激光干扰事件的数量迅速增加，这是由于最近通过互联网可以轻松获得强大，廉价和便携式激光器。航空中的激光照明构成严重的安全和安保风险，对航空乘客和机组人员都有重大影响。激光照射风险产生了新的监管和政策需求，可能会进一步拉伸现有有限的资源和预算来应对这一严重问题。最近，Lamda Guard开发了metaAIR，这是一种介电（非金属）光学超材料过滤器，经过科学设计，可提供激光保护。它由聚合物材料制成，采用纳米图案设计，与入射光相互作用，阻挡和偏转光线，同时提供透明度和上级角度性能。然而，目前的MetaAIR原型受到眩光效应的影响。在这里，我们提出了一个纳米制造的吸收多孔层的metaiR表面上，以减轻眩光效应的基础上，掠射角沉积（GLAD）技术。

Aviation industry worldwide faced a tremendous challenge in increasing the laser attacks on aircraft. Such laser interference incidents have rapidly increased in numbers due to the recent ease of access to powerful, cheap, and portable lasers over the internet. Laser illuminations in aviation pose serious safety and security risks with significant implications to both air passengers and flight crew. The laser illumination risks create a new regulatory and policy need that can further stretch the existing limited resources and budgets to deal with this serious concern. Recently, Lamda Guard developed metaAIR, a dielectric (non-metallic) optical metamaterial filter which has been scientifically engineered to provide laser protection. It has been created from polymer materials using nano-patterned designs which are engineered to interact with incoming light, to block and deflecting it while offering transparency and superior angle performance. However, the current metaAIR prototypes suffers from the glare effect. Here, we are proposing an nanofabricated absorbing porous layer on metaAiR surfaces to mitigate the glare effects based on Glancing Angle Deposition (GLAD) technique.
